Regular honeycomb porous polymer films based on amphiphilic block copolymer

We were first to investigate concentrated micellar solution casting onto solid matrixes based on amphiphilic diblock copolymers. When the concentrated vesicular solution was casting onto glass plate under humid airflow, it forms honeycomb-patterned structure. Furthermore, we attempted to control the honeycomb pattern of the resulting amphiphilic diblock copolymer film via adding the selective solvent content methods. The honeycomb-patterned films have surface roughness and they provide water repellency.
